My son left the RAF last year after 11 years service as a Tech, he suffered quite severe medical problems and was casevaced from Basra just before finishing his 3 month stint, after leaving the RAF he required a period of convalecense before resuming work.His treatment was carried out by the NHS.
He felt that the RAF did not treat him particulaly well, the NHS mislaid medical files etc.
In the end he stumped up for a full BUPA medical report and submitted this, and this resulted in the award of a War Disability one off payment ( with no liability etc etc.)
Best regards,
